Product catalog summary
Main Features of Holtop Rotary Heat Exchanger
  • High efficiency in sensible heat recovery.
  • Double labyrinth sealing system to minimize air leakage.
  • Self-cleaning mechanism extends service life and reduces maintenance costs.
  • Double purge sector reduces carryover from exhaust to supply air.
  • Lifetime-lubricated bearings require no maintenance under normal conditions.
  • Interior spokes reinforce the rotor's laminations.
  • Available rotor diameters range from 500mm to 5000mm, with options for segmentation for easy transport.
  • Selection software available for convenient product selection.
Working Principle

The rotary heat exchanger consists of an alveolate heat wheel, case, drive system, and sealing parts. It facilitates heat and moisture exchange between exhaust and outdoor air as the wheel rotates, achieving energy recovery efficiency between 70% and 90%.

Wheel Materials

The heat wheel is constructed from aluminum foils coated with a 3A molecular sieve, with a thickness of 0.04mm.

Applications

The rotary heat exchanger can be integrated into an air handling unit (AHU) as part of the heat recovery section or installed in ventilation system ducts. The casing type and segment quantity should be chosen based on application space and transportation conditions.

Application Conditions
  • Ambient temperature range: -40°C to 70°C.
  • Maximum face velocity: 5.5m/s.
  • Maximum casing pressure: 2000Pa.

Enthalpy Wheels-1

Enthalpy Wheels Main features of Holtop rotary heat exchanger 1. High efficiency of sensible heat recovery 2. Double labyrinth sealing system ensures minimal air leakage. 3. Self-cleaning efforts prolong service cycle, reducing maintenance cost. 4. Double purge sector minimizes carryover from exhaust air into supply air stream. 5. Life-time-lubricated bearing requires no maintenance under normal usage. 6. Interior spokes are used to mechanically bond the rotor's laminations to reinforce the wheel. 7. Completed range of rotor diameter from 500mm to 5000mm, rotor can be cut into 1pc to 24pcs for easy transportation, various types of housing construction is available as well. 8. Selection software for convenient selection. Working Principle Rotary heat exchanger is composed of alveolate heat wheel, case, drive system and sealing parts. The exhaust and outdoor air pass through half of the wheel separately, when the wheel rotates, the heat and moisture are exchanged between the exhaust and outdoor air. The energy recovery efficiency is up to 70% to 90% Wheel Materials The total heat wheel is made by aluminum foils coated with 3A molecular sieve of 0.04mm thickness. Applications Rotary heat exchanger can built in air handling unit (AHU) as a main part of the heat recovery section. Usually side panel of the exchanger casing is unnecessary, except that bypass has been set in AHU. It can also be installed in the ducts of ventilation system as a main part of the heat recovery section, connected by flange. In this case, side panel of the exchanger is necessary to prevent leakage. Note: casing type and segment quantity should depend on the application spaces as well as transportation capability and conditions at installation. Over segmentation will increase the assembly work, and overlarge size will cause diffculties in transportation. Application conditions - Ambient temperature: -40-70°C - Max face velocity: 5.5m/s - Max pressure on casing: 2000Pa Product link:https://www.holtop.com/enthalpy-wheels.html page 1 / 1 Powered by TCPDF (www.tcpdf.or
